Semiconductor device

A semiconductor device, comprising:

• a semiconductor substrate having a main surface;
• a light receiving element region formed in said main surface of said semiconductor substrate, in which light receiving elements for performing photoelectric conversion are formed;
• a peripheral region formed outside said light receiving element region in said main surface of said semiconductor substrate for performing input/output of an electric signal from/to outside of said semiconductor substrate;
• a boundary region formed between said light receiving element region and said peripheral region as seen in plane;
• a plurality of signal lines arranged in said boundary region for performing input/output of electric signals between said light receiving element region and said peripheral region;
• and
• a conductive layer arranged in a layer different from each of the plurality of said signal lines,
• a relative position of said conductive layer as seen from each of the plurality of said signal lines is all identical, and said conductive layer is all arranged in an identical layer.
